England should know today if captain Mike Tindall will be available or for their attempt on the 6 Nations Grand Slam in Dublin next Saturday (5pm).
The Gloucester centre lifted the Calcutta Cup - handed over by his future mother-in-law, Princess Anne - on Sunday, but then left Twickenham in a protective boot to undergo x-rays.
England delayed any official announcement as to his availability, Tindall having stayed off at half-time of the 22-16 win over Scotland after injuring his ankle in the first half, but he is a major doubt.
If Tindall is ruled out of the Ireland finale then No 8 Nick Easter would be the leading candidate to take over the captaincy.
Wales will hope England lose so that a win in Paris over France would let them share top spot, but England would still almost certainly take the title due to a superior points difference.
